Power Door Locks: Testing: Relay
- To perform relay tests, remove both relay connectors. The relays are located on the lower left side of the instrument panel reinforcer. Ensure that terminal 1 of the relay is grounded. If not, check relay case-to-ground screws for tightness.

- If screws are tight, replace the relay. With a test light connected between terminals 1 and 2, apply power to terminals 2 and 4 of each relay. Do not leave light connected for more than 2 minutes. Test light should light. If not, replace the relay.
